Operating instructions • Load Carrier • 505410638-02 • 07/2019
► Check the tyre inflation pressure regu-
larly according to the manufacturer
specifications and correct if necessary.
The tyre inflation pressure depends on
the technical characteristics of the tyre.
► Observe the supplier documentation.
► Drive only with approved rim and tyre
combinations.
► Observe the seasonal tyres (summer
or winter tyres) for the trailer.
10.2.5 Axle and suspension
► Perform a visual inspection for wear
and damage.
► Have defective or damaged compon-
ents replaced.
► Check the tightening torque of the fix-
ing bolts.
► Observe the maintenance instructions
from the axle manufacturer.
10.2.6 Brake system
WARNING
Risk of accident caused by defective
brakes!
A failure or defect of the brake system can
lead to serious accidents.
► Drive only with properly functioning
brake system.
► In case of defect or wear, park the
trailer immediately.
► Abnormalities or malfunctions of the
brake system must be immediately re-
paired by an authorised specialist
workshop.
► Have the trailer towed if necessary.
Checking the axles/brake system
► Check all bolted connections on new
trailers after repairs, after the first trip
or at the latest after 1,000 km.
► Retighten bolted connections with the
tightening torques specified by the
manufacturer.
► Observe the maintenance instructions
of the installed supplied components.
► Immediately consult an authorised
specialist workshop if there are defects
with the brake or ABS/EBS system
(see "9.2 Fixing braking abnormalities",
pg.106).
Servicing the diagnostics connection
for the EBS brake system
The EBS diagnostics connection is estab-
lished using the EBS plug connector
(ISO7638, 7-pin) at the front of the vehicle.
The diagnosis may only be performed by
an authorised specialist workshop.
► Keep the protective caps closed to
prevent soiling.
Brake pad conditioning
WARNING
Risk of accident due to rear-end colli-
sion!
When performing braking for conditioning,
other road users can collide with the rear
of your trailer and seriously injure them-
selves.
► When performing the braking for con-
ditioning, make sure that other road
users are not endangered by this ac-
tion.
In order to obtain maximum performance
and a long service life for the brake pads,
the brake pads must be in an optimum
condition. It may be necessary to condition
the brake pad for this optimum condition
due to underloading, weather conditions
and when the trailer has been stood idle for
a long period of time.
► As a preventative measure, perform
the conditioning by braking accord-
ingly.
► Procedure:
○ Strong braking and/or dragging brakes
○ Then allow the brake pads to cool
down
○ Repeat in a cyclical loading mode
